I used to think so too, then I had kids :) One interesting approach is to use snooping tools but to then explicitly tell the kids and to discuss the results periodically. I.e., "my job as a parent is to help you figure out how to be a grown up. Part of that is managing money. I noticed you spent money on X and wanted to talk about it" I think for the 'cellphone based GPS-tracking' there was also an explicit rule that…
Keeping your kids safe at all costs isn't good parenting. It encourages suffocating closeness and loss of independence. The point isn't to get your child to the age of 22 without getting criticized for it. The point is to provide the necessary conditions for a successful adult to form. >"my job as a parent is to help you figure out how to be a grown up. Part of that is managing money.

When I grew up it was routine for children to deceive their parents, especially about stuff like friends, smoking, drugs, drinking, sex etc. The assumed parental answer was always no so if you did any of that stuff you had to hide it. It was amazingly easy, we (four brothers) lead our secret lives and the parents mostly had no idea. There are problems with this: if the child gets in a bind there is no way they can ask for advice or help; if the parent finds out and overreacts badly it can seriously damage the relationship. I have a stepfather who I've never contacted since leaving home partly due to this.
Raising our son my wife and I agreed (mostly) that there is no practical way to completely control a _person_ and that trying to do so would just make him hide things from us. We thought the best we could do was to try to instill decent values and good judgment and to avoid useless opposition. This was a bit scary sometimes, "good judgment" and "14 year old boy" are not an obvious combination. He has turned out really well. It may have been just good luck, but I like to think that we avoided a lot of the mistakes our own parents made and that it helped.
As for allowance, we tried to pick a reasonable basic amount for the age and set no conditions. He could earn extra by doing extra work around the house. We also set up "Bank of Dad" where he could save money and get a good return. Learning how to make choices was definitely part of the plan.
Chores were not optional but were not tied to allowance. This was not completely satisfactory as he often delayed chores more than we liked unless cajoled into it somehow. I do this too sometimes.
